Definitions
- the present invention relates generally to gearwheels for the drive of offset press cylinders and more particularly concerns a device for reducing backlash and out-of-true running of the gearwheels.
- DE-PS 2 829 026 discloses a gear drive in which the helical spur gearwheels have a coaxial tensioning disk.
- each tensioning disk has two or more tensioning devices which act axially on the rim of the gearwheel and the elastic axial deformation of the helical gear rim is used to adjust the backlash.
- the gear teeth are tilted somewhat during the axial deformation produced by the tensioning disk.
- the gear rim of the present invention has an annular groove concentric with the gear and open to one side.
- a tensioning ring consisting of two body parts separated by an inner taper is pressed into the annular groove.
- a plurality of tensioning devices are disposed axially on the tensioning ring and, when tensioned, force one of the two body parts of the tensioning ring radially outward due to the action of the inner taper. Radial movement of the tensioning ring causes radial movement of the gear rim. Adjustments can be made until backlash and/or out-of-true running is eliminated.
- FIG. 1 is a partial and generally schematic plan view of a gearwheel according to the invention.
- FIG. 2 is an enlarged and more detailed radial section through the gear rim of the gearwheel taken along line 2--2 in FIG. 1.
- Another important feature of the present invention is the ability to produce a slightly spherical deformation of the gear teeth.
- the spherical deformation takes place because the expanding outer part 11 contacts the gear rim 2 in the middle of the tooth width as illustrated by the arrows B in FIG. 2. This slightly spherical deformation improves the running accuracy of the gears.
